    Hi managers,

    My 3 member cluster under V5.1b PK4 crashed after one member lost one of his
    dimms. cluster_root was badly broken when I tried to rebuild it with fixfdmn
    (from a rescue installation).
    So I rebuilt cluster_root exactly like documented in the "cluster
    administration manual: Troubleshooting clusters" section: make it new but on
    the same disk and with a fresh backup restore.
    I have a rescue system on which the harware view is like on the cluster and
    I can mount any of the filesystems.

    When I try to boot the first member with the orig configuration and
    specifying the maj,min devices:

         vmunix cfs:cluster_root_dev1_maj=19 cfs:cluster_root_dev1_min=277
    clubase:cluster_expected_votes=1 clubase:cluster_qdisk_votes=0
    I get an:
         ..
         Waiting for cluster mount to complete
         panic (cpu 0): cfs_issue_localroot_do_mount: namei on boot partition mp
    failed

    The same is true if I boot the first member (without the kernel clubase:..
    Specifications; this member waits until quorum is reached by another member)
    and crashes as soon as the second member reaches cluster connect also with
    this message.

    I googled for the cfs_issue error without any success.

    Who knows an advice?

    Best regards,

    Rudolf Gabler

While you are able to have cluster member 5 be the failover for all the other instances, there might be a better way to set which member servers can run each instance, but its not difficult to change this at a later date - it might not be an optimal configuration if all the instances are of different memory needs or if you want to handle a situation where more than one cluster member might be unavailable at a time. ...
